Accelerated Experiential Dynamic Psychotherapy (AEDP) Therapists in Markham, Ontario, Canada

Lyonne is a somatic psychotherapist specializing in attachment-based therapy. She works extensively with individuals navigating identity shifts, self-esteem, and life transitions. She supports clients to create meaningful change aligned with their values. Her work centres on regulation, embodiment, and empowerment.

I help adults who feel stuck, overwhelmed, distracted, anxious, or hard on themselves build more clarity, self-understanding, and practical tools for daily life. My style is warm, collaborative, and down-to-earth. I draw from ACT, CBT, and mindfulness-based approaches to help clients better understand their patterns, relate differently to difficult thoughts and emotions, and move toward what matters most.

As a Registered Psychotherapist and Clinical Director of Switzer Counselling & Psychotherapy Associates, I am passionate about providing compassionate, client-centered care that supports meaningful healing and personal growth. With over 20 years of experience in private practice, I have had the privilege of working with children, adolescents, adults, couples, and families facing a wide range of emotional and relational challenges. My therapeutic approach is grounded in evidence-based practices and tailored to meet the unique needs of each individual. I integrate modalities such as EMDR, Sensorimotor Psychotherapy, Emotionally Focused Therapy (EFT), and personality disorder treatment to help clients build resilience, strengthen relationships, and process difficult life experiences in a safe and supportive environment. I believe that therapy is a collaborative journey built on trust, empathy, and authenticity. My goal is to create a space where clients feel heard, understood, and empowered to move toward lasting change and emotional well-being. In addition to my clinical work, I am committed to supporting the growth of the psychotherapy profession through clinical supervision and mentorship of registered professionals and Master’s-level interns. I value ongoing learning, professional development, and fostering strong therapeutic relationships that promote healing and hope.

My passion for psychotherapy comes from my own experiences with relationships. I’ve learned that our greatest joys—and our toughest struggles—often come from the connections we share with parents, partners, children, friends, and colleagues. These relationships shape not only how we see the world but also how we experience ourselves.

Markham is one of the most ethnically Chinese cities in North America outside of East Asia, with a majority Chinese population and a significant South Asian minority, creating a therapy community with unusually strong demand for Mandarin-, Cantonese-, and Punjabi-speaking practitioners. The city is a major technology hub — home to Canadian headquarters for IBM, Apple, and dozens of other multinationals — generating consistent demand for therapists who work with high-performance workplace stress, burnout, and the particular identity pressures of first-generation professionals navigating career expectations between cultures. Markham Stouffville Hospital provides institutional mental health resources, while many residents also access care through the broader Toronto metro therapy ecosystem. Help-seeking stigma in some East Asian communities remains an important context for therapists, who often find themselves helping clients normalize therapy alongside the clinical work.
